    Thats a big tank. What type of system will be used to harvest the rainwater?

    This side of the site will collect rainwater from the roof and parking lot run-off. Downspouts and parking lot will drain into a collection basin, then through a vortex filter before hitting the tank.

    How's the pumping system going to work?

    I want to know what the water is going to be used for.

    I wouldn't think potable water considering it will be gathering nasty stuff off the parking lot.

    On a side note, I've been pushing cistern installs for people this year after the nasty drought we had.

    This is Arizona, it won't be used for potable and certainly not off of a parking lot.

    Landsacping most likely, maybe grey toilet water flush, but even that is an act of god to get passed and approved.

    Rotor-tool- You on the install or just happen to see it? Looks like you have some exclusive site access. Nice project. What type of business?

    do you have to anchor the tanks with concrete? i bid a job that was worried about the groundwater pushing the tanks out of the ground.

    Pretty cool. My son did a science project 10 years ago on the storm water collection systems the county installed. They were similar to catch basins but had separate compartments to collect debris. Turns out the county did not have the money in place to clean them. When my son inquired about that issue they stated it had to be handled as hazardous waste and the money was not available. I chuckled when my son said so basically in a heavy rain the basins flush hazardous waste into the environment. The
    Guys expression was priceless but none the less he agreed. My son received an A for the project and a letter of commendation from the County environmental office for bringing it To the their attention. I am sure the guys installing these tanks have it figured out.

    The tanks like that I've installed called for a specialized gravel backfill that was added as the tanks were being filled to stabilize them. Have heard some horror stories about tanks popping out of the ground, though. :dizzy:

    I get a real kick out of this, "Rainwater Harvesting System", talk. Like this is something new for environmentalists to brag about.
    Can anyone remember the good old "cistern" at farms all across the country?
    sure is a big holding tank for a place that gets, what, maybe 10" of rain in a wet year.
